Pelvic pain/pressure?

Hey...so I'm 24 weeks pregnant with twin boys, which are measuring 25 n 26 weeks! And well ever since I was about 4 months pregnant, I had all this pelvic pain down in my groin but Now it is so intense! At night I can no longer lay on my left side (with my pregnancy pillow) in between my legs, for it hurts too bad. I can lay on my right side for maybe 10 minutes and it gets to where it hurts even worse! Like when I go to roll over it feels like the two bones that run throughmy groin ( I actually refer it as my cooch) are about to shatter! Just walking hurts...feels more of like somebody has a long needle and has a sledge hammer, hammering it right on in! I sit down to out my pants on, I sleep with a pillow in between my leg, I tried doing the whole siting on all four rocking but that's like I might have to call 911 to get me off the floor type pain! The doctor gave me some muscle relaxer to help with back pain and some pressure! Yea it don't work! I called them today and told them I could no longer sleep on my left side and she said that was fine as long as I was comfortable! Which is never cuz if I lay on my back it hurts or I can't breathe! I know it isn't round ligament pains because those hurt around where i had a previous c section! I dunno I'm just at a total loss! Miserable, tired of not being able to roll, get out of bed or off the couch, or be able to dust my bottom part of my coffee table, get in and out of the tub !!! Agh sorry if I rambled and for all typos for I am in bed on my phone! But any great advice or suggestions would be greatly appreciated!
